The Seametrics MJP Series Pulse Water Meters use the multi-jet principle, which has been an internationally-accepted standard for many years. This type of meter is known for its wide range, simplicity, and accuracy in low quality water. The Seametrics MJP Series is certified to NSF/ANSI 61. The impeller is centered in a ring of jets, with inlet jets on one level and outlet jets on another. A gear train drives the register totalizer dials. For pulse output, one of the pointers is replaced by a magnet, which is detected by an encapsulated sensor attached to the outside of the lens. Pulse rate is determined by the dial on which the magnet is placed, and by the number of sensors (single or double).

The MJP Series has a plastic body and is available in 3/4", 1", and 1 1/2" versions. The MJPE meters use a solid-state, long-lasting Hall-effect sensor, which requires power. It is suited for use with Seametrics controls and metering pumps that have sensor power. The MJPR meters use a two-wire reed switch. They provide a dry contact closure and do not require power. The MJPT meters totalize only and do not have a sensor.
